commit a tag points to (both for "release-looking" tags and one with a name
which suggests they're going to do this anyway).
- move all GH_* to the subdirs to make it easier to see what's going on
- use common (and recent) autoconf/automake versions, rather than several
different ones. (client uses cmake not autoconf, but that's ok, the AUTO*_VERSION
variables are just ignored there).
